Step 3: What to do next:
You can use images that you have on your computer (I am assuming I don't have to say anything about copyright stuff here, you know the drill by now - DONT COPY other's work without permission). Print them in black in white or color - it doesn't much matter as you are going to be making copies of them on the copier that will be in black and white.
You are then going to lay the image upside down, meaning that you will be looking at the back of the paper. Now secure it to the fabric with those pins from the supply list.
